Most hypermedia models and systems do not incorporate time explicitly. This prevents authors from having direct control over the temporal aspects of a presentation. In this paper we discuss the concept of presentation time — the timing of the individual parts of a presentation and the temporal relations among them. We argue why time is necessary from a presentation perspective, and discuss its relationship with other temporal views of a presentation. We discuss the requirements and present our solution for incorporating temporal and linking information in a model of time-based hypermedia. KEYWORDS Time-based hypermedia, composition, links, Amsterdam Hypermedia Model, SMIL.
